AIR

Application filed May 9,

To all whom it may concern:

Be it known that I, ROBERT A. TArr, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Air Valves, of which the following is a specification.

My invention relates to air valves and particularly to auxiliary air valves for internal combustion engines, and consists of the novel features herein shown, described and claimed.

My object is to make a valve of the character stated which is a scientific mechanically constructed attachment for all gasoline engines and which will feed the air to the fuel automatically.

In the drawings:

Fig. 1 is a fragmentary perspective showing my device connected to a certain type of engine.

Fig. 2 is an enlarged detail perspeotlve of the connections to the lower end of the steering post.

Fig. 3 is a longitudinal central sectional detail of the device shown in Fig. 2.

Fig. 4 is a fragmentary perspective showing the device connected to the carburetor controlling mechanism, the other parts of the engine being omitted.

Referring to the drawing in detail:

The bowl-shaped shell 1 has a nipple 2 extending from its center. The flat circular plate 3 fits against the top of the bowl 1 and is soldered in place and has a central bearing opening 4 and air holes 5 around the bearing 4. An expansive coil spring 6 rests upon the plate 3. A cylindrical shell 7 fits against the plate 3 and is soldered in place.

A cap plate 8 fits against the cylinder 7 An inner shell 9 fits against the plate 8 and is soldered in place. A valve stem 10 extends slidingly through the plate 3 and through the plate 8.

A head 11 is integral with the stem 10 near its center and presses againt the spring 6. A valve plate 12 is mounted upon the stem 10 against the head 11 which carries a rubber washer 13 and engages the inner end of the shell 9.

Air holes 14 are formed through the plate 8 and the plate is soldered in place. A post 15 extends from the plate 8 parallel with the stem 10. A lever 16 is pivoted to the post 15 and extends through a slot 17 in the VALVE.

stem 10. A rod 18 connects the lever 16 to the arm 19 fixed upon the carburetor controlling rod 20 of the steering post 21.

The rod 18 slides through the arm 19 and is adjusted to the proper length by lock nuts 22 on one side.

The arm 19 is fixed upon the rod 12 beside the arm 23, to which the rod 24 connects the throttle crank 25, the arms extending in opposite directions so that the-rods 18 and 24 operate to pull in opposite directions simultaneously as the throttle is operated.

An elbow 26 is tapped into the intake manifold 27 and then the nipple 2 is screwed into the elbow. The elbow is located so as to bring the rod 18 beside the rod 24.

The parts are adjusted so that when the rod 24 pushes the throttle closed the rod 18 pulls the valve 13 closed and the engine may idle. When the rod 24 pulls the throttle 25 open, then the rod 18 is released and the valve 14 is free to operate under the suction of the engine.

The air around the engine is warm and in passing through the openings 14, the shell 9 and so on, will be fed to the fuel in the manifold 27 By changing the rod 18 and the arm 19 the device may be attached to any engine and will eliminate carbon, keep the spark plugs clean, cool the engine and give more power with less gasoline.

Various changes may be made without departing from the spirit of my invention as claimed.

I claim:

An air intake valve for internal combustion engines comprising an outer shell, means for connecting one end of said shell to an engine intake manifold, an inner shell in the other end of said outer shell in which other end are air inlets communicating with one end of said inner shell, the other end of said inner shell forming a valve seat, a valve rod'extending through said inlet end of said outer shell and through said inner shell, a valve on said rod, a perforated transverse wall in said outer shell between said inner shell and the outlet connecting end of said outer shell, and a spring surrounding said rod between said perforated wall and said valve for normally holding said valve on its seat.
